Positive
  • Revenue growth: Q3 revenue increased 29.4% to $1.2 billion year-over-year.
  • Order momentum and backlog: Orders significantly exceeded revenue in Q3, driven by cloud and large communications service providers.
  • R&D investment: $619.4 million invested in R&D in the first nine months, representing 18.1% of revenue.
  • Capital returns: Board authorized $1.0 billion buyback; ~3.3 million shares repurchased for $245.2 million in the first nine months and additional repurchases of 286,619 shares for $26.4 million through Aug 29, 2025.
  • Debt management: Refinanced $1.16 billion term loan and detailed interest-rate hedges for floating-rate exposure.
Negative
  • Product reallocation charge: Decision to cease forward investment in 25G PON will create an expected $89.1 million non-cash abandonment charge in Q4.
  • Restructuring costs and workforce reduction: Approximately 4% workforce reduction and $20.0 million of restructuring costs anticipated in Q4 of fiscal 2025.
  • Services margin pressure: Services gross margin decreased 320 basis points year-over-year for the nine months, reflecting higher delivery costs.
  • Customer concentration: A single cloud provider accounted for a significant volume of orders, indicating concentration risk.

Insights

TL;DR: Strong top-line growth driven by cloud and CSP demand, healthy R&D investment, and active capital return program support growth thesis.

Ciena delivered 29.4% year-over-year revenue growth in Q3 and double-digit nine-month growth, with notable U.S. strength and continued order/backlog momentum from cloud and large service-provider customers. R&D spending of $619.4 million (18.1% of revenue) signals sustained investment in WaveLogic and platform capabilities that management cites as a competitive differentiator. The $1.0 billion buyback authorization and early repurchases demonstrate shareholder-return discipline. The refinancing of the $1.16 billion term loan and existing 2030 notes maintain a clear debt profile with observable fair-value estimates disclosed.

TL;DR: Operational and product reallocation actions introduce near-term charges and execution risks despite revenue strength.

Management announced cessation of forward investment in 25G PON, which will trigger an $89.1 million non-cash abandonment charge and may require additional asset reviews for inventory and fixed assets. The approved restructuring entails roughly a 4% workforce reduction and an expected $20.0 million of costs in Q4, introducing near-term expense volatility. Services gross margin compression (320 basis points year-to-date) and concentration of orders from a single cloud provider highlight customer and margin risks that could affect future quarterly results.

CIENA CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

(1) INTERIM FINANCIAL STATEMENTS
The interim financial statements for Ciena Corporation and its wholly owned subsidiaries (“Ciena”) included herein have been prepared by Ciena, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”).
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States (“GAAP”) requires Ciena to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena’s estimates and actual results, Ciena’s consolidated financial statements will be affected.
In the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of November 2, 2024 was derived from audited financial statements but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena’s audited consolidated financial statements and the notes thereto included in Ciena’s Annual Report on Form 10-K for the fiscal year ended November 2, 2024 (the “2024 Annual Report”).
Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July, and October, respectively, of each year. Fiscal 2025 is a 52-week fiscal year. Fiscal 2024 was a 53-week fiscal year with the additional week occurring in the fourth quarter.

(2) SIGNIFICANT ACCOUNTING POLICIES
There have been no material changes to Ciena’s significant accounting policies, compared to the accounting policies described in Note 1, Ciena Corporation and Significant Accounting Policies and Estimates, in Notes to Consolidated Financial Statements in Item 8 of Part II of the 2024 Annual Report.

Accounting Standards - Not Yet Effective

In November 2023, the FASB issued ASU No. 2023-07 (“ASU 2023-07”), Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for Ciena’s fiscal 2025 Annual Report on Form 10-K on a retrospective basis. Ciena is currently evaluating the impact of this ASU on its segment disclosures.

In December 2023, the FASB issued ASU No. 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740): Improvement to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. ASU 2023-09 allows for adoption using either a prospective or retrospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03 (“ASU 2024-03”), Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027; however, early adoption is permitted. ASU 2024-03 allows for adoption using either a prospective or retrospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

8


In July 2025, the FASB issued ASU No. 2025-05 (“ASU 2025-05”), Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, to introduce a practical expedient for all entities, which simplifies the calculation required for estimating credit losses and assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods; however, early adoption is permitted. ASU 2025-25 allows for adoption using a prospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

(1) Ciena has forward contracts in place to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net, on the Condensed Consolidated Statements of Operations.
(2) Ciena Corporation, as the U.S. parent entity, uses the U.S. Dollar as its functional currency; however, some of its foreign branch offices and subsidiaries use local currencies as their functional currencies. The related remeasurement adjustments were recorded in interest and other income, net, on the Condensed Consolidated Statements of Operations.

(6) INCOME TAXES

The effective tax rate for the third quarter of fiscal 2025 was higher than the effective tax rate for the third quarter of fiscal 2024, primarily due to the settlement of uncertain tax positions in the prior year.

The effective tax rate for the first nine months of fiscal 2025 was lower than the effective tax rate for the first nine months of fiscal 2024, primarily due to an income tax benefit for share-based compensation expense.

For the nine months ended August 2, 2025, the impact of the 15% global minimum tax, referred to as Pillar Two, was not material to Ciena’s consolidated financial statements.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law in the United States. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions taking effect in fiscal 2025 and others to be implemented through fiscal 2027. The legislation will not have a material impact on Ciena’s consolidated financial statements in fiscal 2025.

Deductions from the reserve for excess and obsolete inventory relate primarily to sales and disposal activities.

(10) DERIVATIVE INSTRUMENTS

Foreign Currency Derivatives 

Ciena conducts business globally in many currencies, and thus is exposed to foreign currency exchange rate changes. To limit this exposure, Ciena enters into foreign currency contracts. Ciena does not enter into such contracts for speculative purposes.

As of August 2, 2025 and November 2, 2024, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability in certain currencies for expenses principally related to research and development activities. The notional amount of these contracts was approximately $325.3 million and $257.0 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges.

As of August 2, 2025 and November 2, 2024, Ciena had forward contracts designated as net investment hedges to minimize the effect of foreign exchange rate movements on its net investments in foreign operations. The notional amount of these contracts was approximately $63.0 million and $65.4 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 36 months or less and have been designated as net investment hedges.

18


As of August 2, 2025 and November 2, 2024, Ciena had forward contracts in place to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. The notional amount of these contracts was approximately $138.5 million and $201.2 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 12 months or less and have not been designated as hedges for accounting purposes.

Interest Rate Derivatives

Ciena is exposed to floating rates of interest on its term loan borrowings (see Note 12 below) and has hedged such risk by entering into floating-to-fixed interest rate swap arrangements (“interest rate swaps”).

In April 2022, Ciena entered into forward starting interest rate swaps to fix the Secured Overnight Financing Rate (“SOFR”) for the first $350.0 million of its floating rate debt at 2.968% from September 2023 through September 2025 (“2025 interest rate swaps”). The total notional amount of the 2025 interest rate swaps was $350.0 million as of August 2, 2025 and November 2, 2024.

In January 2023, Ciena entered into interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.47% through January 2028. The total notional amount of these interest rate swaps was $350.0 million as of August 2, 2025 and November 2, 2024.

In December 2023, Ciena entered into forward starting interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.287% from September 2025 through December 2028 (“2028 forward starting interest rate swaps”). The total notional amount of the 2028 forward starting interest rate swaps effective September 2025 was $350.0 million as of August 2, 2025 and November 2, 2024.

Ciena expects the variable rate payments to be received under the terms of these interest rate swaps to offset exactly the forecasted variable rate payments on the equivalent notional amount of the Refinanced 2030 Term Loan (as defined in Note 12 below). These derivative contracts have been designated as cash flow hedges.

Other information regarding Ciena’s derivatives is immaterial for separate financial statement presentation. See Note 5 and Note 8 above.

Ciena added two new 10-year operating leases to its portfolio in the second quarter of fiscal 2025. The addition of these operating leases increased both operating right-of-use (“ROU”) assets and lease liabilities for fiscal 2025.

(12) SHORT-TERM AND LONG-TERM DEBT

Outstanding Term Loan Payable

Refinanced 2030 Term Loan

Pursuant to a Credit Agreement, dated July 15, 2014, as amended (the “Credit Agreement”), by and among Ciena Corporation, the lenders party thereto and Bank of America, N.A., as administrative agent (the “Administrative Agent”), Ciena maintained a senior secured term loan with an outstanding aggregate principal amount, as of January 17, 2025, of approximately $1.16 billion and maturing on October 24, 2030 (the “2030 Term Loan”).

On January 17, 2025, Ciena Corporation, as borrower, and Ciena Communications, Inc., Ciena Government Solutions, Inc., Ciena Communications International, LLC and Blue Planet Software, Inc., as guarantors, entered into a Refinancing
19


Amendment to Credit Agreement with the lenders party thereto and the Administrative Agent (the “Amendment”), pursuant to which Ciena incurred a new single tranche of senior secured term loans in an aggregate principal amount of approximately $1.16 billion (the “Refinanced 2030 Term Loan”). The proceeds of the Refinanced 2030 Term Loan, together with cash on hand, were used to refinance in full the 2030 Term Loan, including accrued interest, and pay transaction fees and expenses. The Amendment amends the Credit Agreement and provides that the Refinanced 2030 Term Loan will, among other things:

mature on October 24, 2030;
         
amortize in equal quarterly installments in aggregate amounts equal to approximately 0.25% of the principal amount of the Refinanced 2030 Term Loan as of the Closing Date, with the balance payable at maturity;
         
be subject to mandatory prepayment upon the occurrence of certain specified events substantially similar to the 2030 Term Loan, including upon the occurrence of certain specified events such as asset sales, debt issuances, and receipt of annual Excess Cash Flow (as defined in the Credit Agreement);
         
bear interest, at Ciena’s election, at a per annum rate equal to (a) SOFR (subject to a floor of 0.00%) plus an applicable margin of 1.75%, or (b) a base rate (subject to a floor of 1.00%) plus an applicable margin of 0.75%;
         
be repayable at any time at Ciena’s election; and
         
except as described above or otherwise set forth in the Amendment, have substantially identical terms as the 2030 Term Loan.

Except as amended by the Amendment, the remaining terms of the Credit Agreement remain in full force and effect.

The net carrying value of the Ciena’s term loans were comprised of the following as of the date indicated (in thousands):

2030 Term Loan$ $ $ $ $1,148,347 

Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate, through the maturity of the term loans. The amortization of deferred debt issuance costs for the term loans is included in interest expense and was approximately $0.7 million during both the first nine months of fiscal 2025 and fiscal 2024.

As of August 2, 2025, the estimated fair value of the Refinanced 2030 Term Loan was $1.15 billion. Ciena’s term loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its term loan using a market approach based on observable inputs, such as current market transactions involving comparable securities.

Outstanding Senior Notes Payable

2030 Notes

On January 18, 2022, Ciena entered into an indenture among Ciena, as issuer, certain domestic subsidiaries of Ciena, as guarantors, and U.S. Bank National Association, as trustee, pursuant to which Ciena issued $400.0 million in aggregate principal amount of 4.00% fixed-rate senior notes due 2030 (the “2030 Notes”).

The net carrying value of the 2030 Notes was comprised of the following as of the dates indicated (in thousands):

Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate, through the maturity of the 2030 Notes. The amortization of deferred debt issuance costs for the 2030 Notes is included in interest expense and was approximately $0.5 million during both the first nine months of fiscal 2025 and fiscal 2024.

As of August 2, 2025, the estimated fair value of the 2030 Notes was $376.5 million. The 2030 Notes are categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2030 Notes using a market approach based on observable inputs, such as current market transactions involving comparable securities.

(14) EARNINGS PER SHARE CALCULATION

Basic net income per common share (“Basic EPS”) is computed using the weighted average number of common shares outstanding. Diluted net income per potential common share (“Diluted EPS”) is computed using the weighted average number of the following, in each case, to the extent that the effect is not anti-dilutive: (i) common shares outstanding; (ii) shares issuable upon vesting of stock unit awards; and (iii) shares issuable under Ciena’s employee stock purchase plan, using the treasury stock method.
The following table presents the calculation of Basic EPS and Diluted EPS for the periods indicated (in thousands, except per share amounts):

(15) STOCKHOLDERS’ EQUITY

Stock Repurchase Program

On October 2, 2024, Ciena announced that its Board of Directors authorized a three-year program to repurchase up to $1.0 billion of its common stock, commencing in fiscal 2025 and continuing through the end of fiscal 2027.

During the first nine months of fiscal 2025, Ciena repurchased approximately 3.3 million shares of its common stock for an aggregate purchase price of approximately $245.2 million, which equates to an average price of $75.02 per share. As of August 2, 2025, Ciena has an aggregate of $754.8 million authorized and remaining under its stock repurchase program. Ciena is required to allocate the purchase price for the shares of Ciena’s stock repurchased as a reduction of common stock and additional paid-in capital.

Stock Repurchases Related to Stock Unit Award Tax Withholdings
Ciena repurchases shares of its common stock to satisfy employee tax withholding obligations due on vesting of stock unit awards. The related purchase price of $60.0 million for the shares of Ciena’s stock repurchased during the first nine months of fiscal 2025 is reflected as a reduction to stockholders’ equity. Ciena is required to allocate the purchase price of the repurchased shares as a reduction of common stock and additional paid-in capital.

(18) COMMITMENTS AND CONTINGENCIES

Tax Contingencies
Ciena is subject to various tax contingencies arising in the ordinary course of business. Ciena does not expect that the ultimate settlement of these contingencies will have a material effect on its financial position or cash flows.

Litigation

Ciena is subject to various legal proceedings, claims, and other matters arising in the ordinary course of business, including those that relate to employment, commercial, tax, and other regulatory matters. Ciena is also subject to intellectual property related claims, including claims against third parties that may involve contractual indemnification obligations on the part of Ciena. Ciena does not expect that the ultimate costs to resolve such matters will have a material effect on its results of operations, financial position, or cash flows.
Purchase Obligations
Ciena has certain advanced commitments for supply of certain long lead time components. As of August 2, 2025, Ciena had $1.8 billion in outstanding purchase commitments to contract manufacturers and component suppliers for inventory. In certain instances, Ciena is permitted to cancel, reschedule or adjust these commitments. Consequently, only a portion of this amount relates to firm, non-cancelable and unconditional obligations.
(19) SUBSEQUENT EVENTS

Stock Repurchase Program

From the end of the third quarter of fiscal 2025 through August 29, 2025, Ciena repurchased 286,619 shares of its common stock for an aggregate purchase price of $26.4 million at an average price of $92.10 per share, inclusive of repurchases pending settlement under its current stock repurchase program. As of August 29, 2025, Ciena has an aggregate of $728.4 million of authorized funds remaining under this repurchase program.

Reallocation of Innovation Investment and Fiscal 2025 Restructuring Plan
On August 26, 2025, in order to align Ciena’s strategic investments with our highest-growth demand opportunities, its executive team determined to cease forward investment in certain broadband development initiatives, primarily 25G PON, within the routing and switching product line of the Network Platforms operating segment. Ciena intends to continue support and development of its 10G PON-based products.
Ciena’s executive team also approved a restructuring plan intended to deliver increased operating efficiencies and, as a result, commencing during the fourth quarter of fiscal 2025, Ciena is implementing a workforce reduction of approximately 4%
24


to 5% of its global headcount, which includes employees associated with the broadband development initiatives discussed above.
The estimated cash cost related to these actions is approximately $20.0 million and represents employee severance and related costs. As such, we expect an expense of approximately $20.0 million to be incurred in the fourth quarter of fiscal 2025. In addition, Ciena anticipates that its decision to cease future investment in 25G PON will result in a non-cash charge in the fourth quarter of fiscal 2025 related to the abandonment of its in-process R&D intangible asset, which has a carrying value of $89.1 million as of August 2, 2025. During the fourth quarter of fiscal 2025, Ciena will also evaluate the impact of these actions on other assets including, but not limited to, inventory and fixed assets.

We are a network technology company, providing hardware, software, and services to a wide range of network operators and enabling enhanced network capacity, service delivery, and automation. Our solutions support network traffic across a wide range of applications, including cloud, video, data, artificial intelligence (“AI”), and voice. Our network solutions are used globally by communications service providers, cable and multiservice operators, cloud providers, submarine network operators, governments, and enterprises across multiple industry verticals. Our portfolio is designed to enable the Adaptive Network™, which is our vision for a network end state that leverages a programmable and scalable network infrastructure, driven by software control and automation capabilities, that is informed by network analytics and intelligence. Our solutions include Networking Platforms, including our Optical Networking portfolio and our Routing and Switching portfolio, which can be applied from the network core to end-user access points, and which allow network operators to scale capacity, to increase transmission speeds, to allocate traffic efficiently, and to adapt dynamically to changing end-user service demands. To complement our Networking Platforms, we offer Platform Software, which includes our Navigator Network Control Software (NCS) and advanced applications that deliver multi-layer domain control and operations for network operators. Through our Blue Planet Automation Software, we also enable complete service lifecycle management automation with productized operational support systems, including inventory, orchestration and assurance solutions that help our customers to achieve closed loop automation across multi-vendor and multi-domain environments. In addition to our systems and software, we also offer a broad range of services that help our customers build, operate, and improve their networks and associated operational environments. These include network transformation, consulting, implementation, systems integration, maintenance, network operations center (NOC) management, learning, and optimization services.

Market Opportunity and Investment in Technology Innovation

The market into which we sell our communications networking solutions is dynamic and is characterized by a high rate of change, including rapid growth in bandwidth demand and network traffic, the proliferation of cloud-based services, and new approaches, or “consumption models,” for designing and procuring networking solutions. Drivers of increased bandwidth demand include enterprise and consumer cloud network adoption, AI, 5G, high-definition video, and network operator focus on resilience and automation. To address these growing service demands and manage network cost, many network operators are looking to adopt next-generation infrastructures that are more programmable and better capable of leveraging data for network insight, analytics and automation.

We believe that our investment capacity and our efforts to push the pace of innovation are important competitive differentiators in our markets. Keeping pace with the market’s demand for technology innovation requires considerable research and development investment capacity and expenditures, and research and development spending represented 18.1% of our revenue in the first nine months of fiscal 2025. During the first nine months of fiscal 2025, we invested $619.4 million in research and development activities, an increase of 8.4% compared to the first nine months of fiscal 2024. In particular, in an effort to capture certain market opportunities created by the impact of AI on networks, we have continued to innovate, increase the performance of, and enhance the capabilities for our leading WaveLogicTM coherent modem technology in multiple form factors. Through this innovation, we seek to extend our leadership in our core business and leverage this to expand our addressable market into complementary and adjacent network applications, including inside and around the data center.

Business Momentum

The optical component industry has been experiencing increased demand, in particular as a result of cloud provider expenditures related to AI and other applications. This increased demand has led to an industry-wide constrained supply environment with extended lead times, resulting in some customers accelerating future orders.

During the third quarter of fiscal 2025, we continued to experience broad-based business momentum, with orders for our products and services significantly exceeding our revenue, resulting in increased backlog. We believe some portion of this order growth was impacted by the industry dynamics described above. We experienced year-over-year order growth in our major customer segments, particularly with cloud provider customers and large communications service provider customers, with a single cloud provider customer continuing to provide a significant volume of orders. As a result, our revenue increased by 29.4% to $1.2 billion in the third quarter of fiscal 2025 as compared to $942.3 million in the third quarter of fiscal 2024. Two of our top five customers by revenue for the third quarter of fiscal 2025 were cloud providers. Although our business remains subject to quarterly fluctuations due to customer purchasing patterns and supply chain dynamics, we continue to believe that certain trends and shifts in business and consumer behaviors and the drivers of bandwidth demand described above under the heading “Overview - Market Opportunity and Investment in Technology Innovation” in this Item 2 represent long-term opportunities for our business.

These currency fluctuations had a positive effect on our revenue reported in U.S. Dollars of approximately $3.6 million, or 0.3%, as compared to the third quarter of fiscal 2024, and had an adverse effect on our revenue reported in U.S Dollars of approximately $5.6 million, or 0.2%, as compared to the first nine months of fiscal 2024.

Cost of Goods Sold and Gross Profit

There are a number of important factors or conditions that can adversely affect or cause our gross profit as a percentage of product or service revenue, or “gross margin,” to fluctuate on a quarterly basis. For example, early stages of new network builds also often include an increased concentration of lower margin “common” equipment, photonic line systems, and installation services, with the intent to improve margin as we sell channel cards, advanced software, and maintenance services to customers as they add capacity. In addition, products that are in early or introductory phases may carry lower margins. The component elements that comprise our product cost of goods sold and services cost of goods sold, and certain factors that can cause gross margin to fluctuate, are described in detail in the “Consolidated Results of Operations - Cost of Goods Sold and Gross Profit” in Item 7 of Part II and “Risk Factors” in Item 1A of Part I of our 2024 Annual Report.

The tables below set forth the changes in revenue, cost of goods sold and gross profit for the periods indicated (in thousands, except percentage data):

Quarter ended August 2, 2025 as compared to the quarter ended July 27, 2024
Gross profit increased by $99.1 million. Gross margin decreased by 160 basis points, primarily reflecting decreased services margins.
Gross profit on products increased by $100.8 million from $296.0 million for the third quarter of fiscal 2024 to $396.8 million for the third quarter of fiscal 2025. Product gross margin of 40.6% did not change for the third quarter of fiscal 2025 as compared to the third quarter of fiscal 2024. However, in the third quarter of fiscal 2025, we experienced unfavorable product mix partially offset by improved manufacturing efficiencies and product cost reductions, as compared to the third quarter of fiscal 2024.
Gross profit on services decreased by $1.7 million from $108.0 million for the third quarter of fiscal 2024 to $106.3 million for the third quarter of fiscal 2025. Services gross margin decreased by 690 basis points, from 50.7% for the third quarter of fiscal 2024 to 43.8% for the third quarter of fiscal 2025, primarily due to increased costs related to delivering maintenance arrangements.
Nine months ended August 2, 2025 as compared to the nine months ended July 27, 2024

Gross profit increased by $168.2 million. Gross margin decreased by 180 basis points, reflecting decreased products and services margin.
Gross profit on products increased by $158.5 million from $950.9 million for the first nine months of fiscal 2024 to $1.11 billion for the first nine months of fiscal 2025. Product gross margin decreased by 140 basis points, from 42.0% for the first nine months of fiscal 2024 to 40.6% for the first nine months of fiscal 2025, primarily due to unfavorable product mix, partially offset by manufacturing efficiencies.
Gross profit on services increased by $9.7 million from $308.7 million for the first nine months of fiscal 2024 to $318.4 million for the first nine months of fiscal 2025. Services gross margin decreased by 320 basis points, from 49.5% for the first nine months of fiscal 2024 to 46.3% for the first nine months of fiscal 2025, primarily due to increased costs related to delivering maintenance arrangements.

Quarter ended August 2, 2025 as compared to the quarter ended July 27, 2024
Research and development expense increased by $23.0 million. Net of hedging, this increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation, partially offset by lower prototype expense.
Selling and marketing expense increased by $27.2 million. This increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation.
General and administrative expense increased by $2.3 million. This increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation, partially offset by lower legal fees.
Significant asset impairments and restructuring costs remained relatively unchanged.
Amortization of intangible assets remained relatively unchanged.
Nine months ended August 2, 2025 as compared to the nine months ended July 27, 2024
Research and development expense increased by $47.9 million. Net of hedging, this increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation, and professional services related to design engineering, fabrication and production of ASIC chips, partially offset by lower prototype expense.
31


Selling and marketing expense increased by $51.2 million. This increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation, and increases in travel and entertainment costs.
General and administrative expense increased by $8.9 million. This increase primarily reflects increases in employee-related compensation costs primarily due to increases in incentive compensation, partially offset by lower legal fees and bad debt expense.
Significant asset impairments and restructuring costs decreased by $16.7 million primarily due to a reduction in restructuring activities. For more information on our restructuring costs, see Note 4 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
Amortization of intangible assets decreased by $2.7 million, primarily reflecting certain intangible assets having reached the end of their economic lives.

Currency Fluctuations
During the third quarter and first nine months of fiscal 2025, approximately 47.7% and 48.2% of our operating expense was non-U.S. Dollar-denominated, respectively. During the third quarter and first nine months of fiscal 2025, as compared to the third quarter and first nine months of fiscal 2024, the U.S. Dollar fluctuated against other currencies. These currency fluctuations, net of hedging, had the effect of reducing our operating expense by a negligible amount as compared to the third quarter of fiscal 2024, and $12.3 million, or 1.0% as compared to the first nine months of fiscal 2024.

Segment Profit (Loss)
Segment profit (loss) is determined based on internal performance measures used by our chief executive officer to assess the performance of each operating segment in a given period. In connection with that assessment, the chief executive officer excludes the following items: selling and marketing costs; general and administrative costs; significant asset impairments and restructuring costs; amortization of intangible assets; interest and other income, net; interest expense; loss on extinguishment and modification of debt; and provision for income taxes.

Liquidity and Capital Resources
33


Based on past performance and current expectations, we believe that cash from operations, cash, cash equivalents, investments, and other sources of liquidity, including our Revolving Credit Facility (as defined below), will satisfy our currently anticipated working capital needs, capital expenditures, and other liquidity requirements associated with our operations through the next 12 months and the reasonably foreseeable future. We regularly evaluate our capital structure, liquidity position, debt obligations, and anticipated cash needs to fund our operating or investment plans or increase our strategic flexibility, and we will continue to consider capital raising and other market opportunities.
Principal Sources of Liquidity. Our principal sources of liquidity on hand include our cash, cash equivalents, and investments, which, as of August 2, 2025, totaled $1.4 billion, as well as the unused portion of our senior secured revolving credit facility (the “Revolving Credit Facility”), to which we and certain of our subsidiaries are parties. The Revolving Credit Facility provides for a total commitment of $300.0 million with a maturity date of October 24, 2028. We principally use the Revolving Credit Facility to support the issuance of letters of credit that arise in the ordinary course of our business and for general corporate purposes. As of August 2, 2025, letters of credit totaling $52.1 million were issued under the Revolving Credit Facility. There were no borrowings outstanding under the Revolving Credit Facility as of August 2, 2025.
Foreign Liquidity. The amount of cash, cash equivalents and short-term investments held by our foreign subsidiaries was $539.5 million as of August 2, 2025. Approximately $92.1 million of future cash generated from these foreign subsidiaries is expected to be repatriated, with any remaining amount continuing to be indefinitely reinvested. A deferred tax liability related to the expected repatriation amount was accrued in fiscal 2023. There are no other significant temporary differences related to our investment in the foreign subsidiaries for which a deferred tax liability has not been recognized.
Stock Repurchase Authorization. On October 2, 2024, we announced that our Board of Directors authorized a program to repurchase up to $1.0 billion of our common stock, which replaced in its entirety the previous stock repurchase program authorized in fiscal 2022. During the first nine months of fiscal 2025, we repurchased $245.2 million of our common stock under the stock repurchase program, and $754.8 million remained under the current repurchase authorization as of August 2, 2025. The amount and timing of any further repurchases under our stock repurchase program are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions. The program may be modified, suspended, or discontinued at any time. See Note 15 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report as well as Item 2 of Part II of this report.

Total cash, cash equivalents, and investments in marketable debt securities$1,390,753 $1,332,126 $58,627 

Cash, cash equivalents and investments increased by $58.6 million during the first nine months of fiscal 2025. Cash from operating activities generated $435.0 million which was partially offset by the following: (i) cash used for stock repurchases under our stock repurchase program of $250.0 million; (ii) cash used to fund our investing activities for capital expenditures totaling $95.4 million; (iii) stock repurchases on vesting of our stock unit awards to employees relating to tax withholding of $60.0 million; and (iv) cash used for payments on our term loan due October 28, 2030 of $8.7 million. In addition to cash provided by operating activities, proceeds from the issuance of equity under our employee stock purchase plan provided $35.9 million in cash during the nine months ended August 2, 2025.

Cash Provided By Operating Activities
The following sections set forth the components of our $435.0 million of cash provided by operating activities during the first nine months of fiscal 2025. Net income (adjusted for non-cash charges) provided cash of approximately $369.5 million and cash provided by operating assets and liabilities was approximately $65.5 million.

 Total cash provided by operating assets and liabilities$65,551 

As compared to the end of fiscal 2024, for the first nine months of fiscal 2025:

The change in accounts receivable primarily reflects the timing of cash collections from customers and increased sales volume;
The change in inventories primarily reflects increases in raw materials;
The change in prepaid expenses and other primarily reflects reduced refundable cash advances to a third-party contract manufacturer partially offset by increased contract assets for unbilled accounts receivable;
The change in accounts payable, accruals, and other obligations primarily reflects a higher accrual associated with our annual incentive compensation plan, the timing of payments to suppliers and the timing of payments for payroll, partially offset by timing of payments for income taxes;
The change in deferred revenue primarily represents an increase in advanced payments received on multi-year maintenance contracts from customers prior to revenue recognition; and
The change in operating lease assets and liabilities, net, represents cash paid for operating lease payments in excess of operating lease costs.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

    The information set forth under the heading “Commitments and Contingencies - Litigation” in Note 18 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report, is incorporated herein by reference.

Item 1A. Risk Factors

Investing in our securities involves a high degree of risk. Before investing in our securities, you should consider carefully the information contained in this report and in our 2024 Annual Report, including the information under “Risk Factors” in Item 1A of Part I thereof. This report contains forward-looking statements that involve risks and uncertainties. See “Management’s Discussion and Analysis of Financial Conditions and Results of Operations – Cautionary Note Regarding Forward-Looking Statements” in Item 2 of Part I of this report. Our actual results could differ materially from those contained in the forward-looking statements. Any of the risks discussed in our 2024 Annual Report, in this report, in other reports we file with the SEC, and other risks we have not anticipated or discussed, could have a material adverse impact on our business, financial condition, or results of operations. Except as set forth below, there has been no material change to the material factors that make an investment in our securities speculative or risky from those presented in our 2024 Annual Report.

Tariffs and other import measures imposed by the United States or other countries may adversely affect our business, operations, and financial results.
In January 2025, the U.S. government commenced a broad review of U.S. trade relations and began imposing, or threatening to impose, tariffs on certain countries, materials, and industries. In response, certain impacted countries have imposed or threatened various retaliatory tariffs or other trade restrictions. We rely on a global sourcing strategy and third-party contract manufacturers outside of the United States to perform substantially all of our manufacturing. Moreover, revenue in the United States represented approximately 70% of our revenue in fiscal 2024. Significant changes to trade policy, the imposition of tariffs, or retaliatory responses thereto, have adversely impacted and could materially adversely impact our business, operations, and financial results, including by increasing our costs, by decreasing our profit margins, and/or by making our products less competitive. The tariff policy environment has been and can be expected to continue to be dynamic. Tariffs recently implemented that have impacted or could materially impact our business include tariffs on imports:
from Canada and Mexico, as products making up a significant portion of our revenue are manufactured in or distributed from Mexico, and we generally introduce new products and conduct related early volume manufacturing in Canada;
of steel, aluminum, and copper, including derivative goods that include certain of our products;
from China, as our supply chain includes certain China-based suppliers; and
from a wide range of countries globally, including Thailand and Vietnam, where we also rely on third-party manufacturing operations for a significant portion of our revenue.
37


Additionally, we currently rely upon certain trade agreements and product or technology based exemptions that reduce our tariff exposure. The U.S. government is currently investigating imports of a range of different products, including semiconductors and critical raw minerals, and derivative products relevant to our business and products, which could result in material additional tariffs. There can be no guarantee as to which of our products will be impacted by new or changing tariffs, or that they will remain eligible for exceptions under existing or future trade agreements or executive orders.
We have taken steps, and may take additional steps, to attempt to mitigate the impact of tariffs on our business, including: by availing ourselves of certain exemptions to tariffs; by making changes to our supply chain practices, sources of supply, or manufacturing locations; and by passing the cost of tariffs to customers. These changes could take considerable time to implement, result in significant costs, and cause supply chain delays or disruption. Moreover, there can be no assurance as to customer reaction to the current trade environment, the imposition of new tariffs, or any tariff mitigation steps we elect to take. Among other things, customers may elect to reduce spending, renegotiate contracts, defer orders or delivery of existing orders, or shift purchases to other vendors, each of which would adversely impact our financial results and competitive position with customers.
Certain tariffs that have been implemented or proposed are subject to legal challenges, but there can be no assurance that such challenges will be successful or that, if successful, additional or alternative tariffs will not be imposed. The results of such legal challenges, including any potential resulting retroactive changes to tariffs, could adversely impact our financial results.
